This paper presents a procedure to perform the risk analysis for ground failure by liquefaction. The liquefaction is defined as the result of cumulative damage caused by seismic loading. The fatigue life of soil can be determined on the basis of the N-S relationship and Miner`s cumulative damage law. The rain-flow method is used to count the number of cycles of stress response of the soil deposit. Finally, the probability of liquefaction is obtained by integrating over all the possible ground motion and the fragility curves of liquefaction potential.
